The objective of this study was to identify the species of thrips associated with rice crops in order to determine population fluctuation of the dominant species. Studies were conducted during the month of April to August in the year 2017 form different growth stages of rice in Babolsar city, Mazandaran Province (Northern Iran). Samplings were done from four fields located at two sites, KeyxaMahalle and MirBazar. A total of seven species of thrips belonging to four genera and two families (Thripidae and Phlaeothripidae) were identified. Amongst them, Haplothrips eragrostidis Priesner was the dominant species accounting for 75.47% in abundance. This was followed by Thrips hawaiiensis Morgan comprising 6.47%. The other species include Anaphothrips sudanensis Trybom, Frankliniella intonsa (Trybom), F. tenuicornis (Uzel), Thrips tabaci Lindeman and Haplothrips flavicinctus (Karny) which comprised of4.85%, 4.32%, 4.31%, 4.04% and 0.54% respectively. The maximum number of thrips species was found in the middle of July and minimum in the month of May. Assessment of thrips abundance in rice fields were started at the beginning of dough stage and were continued until complete maturity.

In order to extend the work on Iranian Collembolan fauna, several samplings from leaf litter and soils conducted in Ilam province (west of Iran). Specimens were collected from different localities and extracted by Berlese funnels. Results from the study lead to identification of 11 species of five families: Onychiuridae (with two genera and two species), Tullbergiidae (with one genus and one species), Hypogastruridae (with one genus and one species), Isotomidae (with four genera and four species) and Entomobryidae (with one genus and one species). Sminthurus muscicolus Betsch, 1977 from Sminthuridae was new for Iranian fauna. All species from the present study reported for the first time from Ilam province. Short explanation of each collected species including the material studied, a distribution and a short description for the new record and some illustrations are given.

The genus Taeniothrips Amyot & Serville is belonging in the subfamily Thripinae with only one species in Iran. Here, the second species, T. eucharii (Whetzel) is newly recorded from the country. Male and female specimens of this species have been collected on the flowers of Ixiolirion tataricum (Amaryllidaceae) from Ilam province (west of Iran).

This study was done during 2012 to 2014 to determine the species composition of thrips on fruit trees and weeds of orchards in three counties of Qazvin Province (i.e. Buin-Zahra, Takestan and Qazvin). For each county 14 orchards were sampled. In each orchard, 10 trees and from each tree four shoots along with their leaves, flowers and fruits were selected as a sample unit. Diversity was calculated by Shannon-Wiener Index and evenness by Pielou evenness index. Species richness was estimated using the first-order jackknife richness estimator. One-way ANOVA was used to test whether there exists significant variation in species diversity, evenness and richness along the three counties. Of the 4,489 adult collected specimens from three locations, 27 species belonging to 13 genera were identified. The highest number of thrips was collected on plants of family Rosaceae, followed by Vitaceae and Moraceae, respectively. The number of collected species in Qazvin (18) and Buin-Zahra (17) counties were more than Takestan (13) county. Similar trend was observed for the total number of adult specimens collected in the three counties as more specimens were found in Qazvin and Buin-Zahra than Takestan. Results of this study showed that Thrips tabaci L. was found on all species of fruit trees and weeds. There were no significant differences among the three counties in terms of both diversity (P = 0.41) and evenness (P = 0.45). Across the counties, thrips estimated richness was higher in Qazvin county compared to Buin-Zahra and Takestan counties. Among the trees in Buin-Zahra and Takestan counties, grape had the highest thrips diversity. The highest value of diversity for Qazvin county was recorded for apricot. The polyphagous species T. tabaci was dominant in all three counties, followed by Frankliniella occidentalis (Pergande) (in Qazvin county), Frankliniella intonsa (Trybom) (in Buin-Zahra county) and Frankliniella tenuicornis (Uzel) (in Takestan county).

The genus Thrips Linnaeus (Thysanoptera: Thripidae) with 37 species, is the largest genus in Thripinae from Iran. However, Thrips coloratus Schmutz was excluded from Iranian thrips because of its misidentification. Here, this species is recorded from Iran for the first time based on two specimens collected on the flowers of clover (Fabaceae) from Ilam province.

The American species, Tylothrips osborni (Hinds) is reported for the first time from Iran and presented with detailed photos. The single macropterous female, which has been collected in the Ilam province, shows an unusual variation regarding the number of sense cones on antennal segment III. This variation affects both antennae in form of a reduction of the number of sense cones.

Montpellier maple Acer monspessulanum L. is one of the trees in Zagros forests (Iran) which is host to several economically important thrips species. The purpose of this study was to find the fauna of thrips on Montpellier maple trees in Ilam province, western Iran, during 2015-2016. The abundance and species diversity of thrips were examined twice a month via standard sweep net and shaking flowers and leaves to white plastic tray at two location sites including Gachan and Manesht Mountains. Out of the 7062 thrips specimens that were collected, 16 thrips species were identified, which belonged to 10 genera and four families. The estimated domination coefficient showed that in both sites Taeniothrips inconsequens Uzel was eudominant and onion thrips, Thrips tabaci Lindeman was dominant species. There were 5 and 4 species classified as subdominant for Gachan and Manasht, respectively. Four predatory thrips were found on Montpellier maple trees including Aeolothrips intermedius Bagnall, Scolothrips longicornis Priesner, Haplothrips flavitibia Williams and H. globiceps. Of these, A. intermedius was the most abundant predator in both collection sites, whereas others showed a low population density. According to diversity index calculations, the Shannon diversity, Pielou’s evenness and Margalef’s species richness indices were 1.83, 0.68 and 1.67 for Gachan, and 1.48, 0.62 and 1.26 for Manesht, respectively.

The present list is based on all available published literatures on taxonomy and biodiversity of the thrips fauna of China (including Taiwan, Hong Kong and Macau) up to July 2024. The known Chinese Thysanoptera fauna currently consists of 816 species in 206 genera, including 443 species in the suborder Terebrantia and 373 species in the suborder Tubulifera. In addition, the family Stenurothripidae Bagnall has been added to the fauna of China. In the past 10 years, many additional taxa have been newly recorded or described for China, that is includes about 12.6% of all species of thrips in the world. Amongst Chinese taxa, the family Thripidae is the most diverse, with 412 species, and within this family, the richest genera are Thrips, Stenchaetothrips, Mycterothrips and Trichromothrips, respectively. Totally, the most species have been recorded from Taiwan, with 292 records, followed by Yunnan, with 273 records, and Guangdong, with 237 records.
